Why? Good question and this can be a solution.
Many plumbers genuinely believe that if there solder joints look better than their peers they are an improved plumber. Trust in me when I inform you, many plumbers are extremely condescend and competitive plus in reality a good looking solder joint takes time and training.
Secret Step that is 6th that Improve Your Solder Finishes.
Once you’ve filled your hub with solder you’re going to begin to see the solder type and begin to dry across the hub and might overflow and run even over the fitting. Some tips about what you will need to do while having readily available.
You will need a cloth that is damp known as a wiping towel or any old rag is going to do.
You also need a spray bottle full of water.
While the solder remains in its form that is molten take damp fabric and wipe the solder across the hub. During the same time as you wipe your goal is to try to push just as much of the solder to the hub of the fitting. Be careful as the solder, suitable and pipe have become hot.

Now that the tops are tabbed, flip them over (sunny side down), but, slip out of the tabbing strip through the first one therefore it lays over the back for the next. Perform some same most of the real way down your “string”. You will be soldering the strip to the contact points regarding the relative back of this cells. In case your cells are like mine, you will have 6 tiny contact that is whitish. Make fully sure your tab strips line up so they really will sit on the contact spots then use flux to your spots. Hold your soldering iron to your strip at that moment and when its hot, touch the solder wire to your point and allow the solder flow, do not use way too much and do not over temperature the contact since you may harm the cell. An alternative is by using a solder paste regarding the contact, lay the tab on and support the iron in the point till it flows, for me, this was an improved solution. Perform some same for several six contact points, now have two cells linked. Continue doing this process for all your solar panels along the string.
This is a pretty idea that is good be sure you have good solder connections, by exposing the cells to light and testing the production voltage. At the minimum, check each string, its too late if you have connected them all up to get you’ve got a solder that is”dry someplace and possess to locate it right back. With the sequence of cells all soldered together, there is something else to do. At this stage you will have at one end associated with string, the very last one, featuring its “top tabs” free. But at the beginning of the sequence, absolutely nothing to connect to. So that you have to solder a length that is short of strip towards the straight back of this “top” (first) cellular to have one thing in order to connect to and complete a circuit. So, on the “first” cell, solder tabbing strips across the back connections with an adequate amount of a free end to enable you something for connecting to. Now you are going to have connecting tabs at both ends of your sequence ready to connect with its neighboring sequence or a connector bus. Really, now you have check this out far, its a good concept to accomplish solder this “first” set of back tabs before soldering up a string, it saves some double control.
